+## Image Optimizer Default Settings
+
+[Fastly Image Optimizer](https://docs.fastly.com/products/image-optimizer) (Fastly IO) is an [image optimization](https://www.fastly.com/learning/what-is-image-optimization) service that manipulates and transforms your images in real time and caches optimized versions of them.
+
+Fastly Image Optimizer supports a variety of image formats and applies specific settings to all images by default. These can be controlled with this API or the [web interface](https://docs.fastly.com/en/guides/about-fastly-image-optimizer#configuring-default-image-settings). Changes to other image settings, including most image transformations, require using query string parameters on individual requests.
+
+The [Image Optimizer default settings](https://developer.fastly.com/reference/api/services/image-optimizer-default-settings/) API allows customers to configure
+default settings for Image Optimizer requests, configuring the way images are optimized when not overridden by URL parameters on specific requests.
+
+The service must have the Image Optimizer product enabled using the Product Enablement API, UI, or Terraform block to use the `image_optimizer` block.
+
+## Example Usage
+
+Basic usage:
+
+```terraform
+resource "fastly_service_vcl" "demo" {
+  name = "demofastly"
+
+  domain {
+    name    = "demo.notexample.com"
+    comment = "demo"
+  }
+
+  backend {
+    address = "127.0.0.1"
+    name    = "localhost"
+    port    = 80
+  }
+
+  product_enablement {
+    image_optimizer = true
+  }
+
+  image_optimizer_default_settings {
+    resize_filter = "lanczos3"
+    webp = false
+    webp_quality = 85
+    jpeg_type = "auto"
+    jpeg_quality = 85
+    upscale = false
+    allow_video = false
+  }
+
+  force_destroy = true
+}
+```
+
+All fields in `image_optimizer_default_settings` are optional.
+
+NOTE: When added, `image_optimizer_default_settings` will always set all default settings. This will replace any settings previously changed in the UI or API.
+
+## Delete
+
+Deleting the resource will reset all Image Optimizer default settings to their default values.
+
+If deleting the resource errors due to Image Optimizer no longer being enabled on the service, then this error will be ignored.
+
+When Image Optimizer is next re-enabled on a service, that service's Image Optimizer default settings will be reset - so a disabled service effectively already
+has deleted/default Image Optimizer default settings.
